I am having the same problem.
So I can confirm.
Comment 6 Carlos Salvador Pérez Salgado 2017-06-15 13:59:24 UTC
This patch has been proposed to fix the issue:

Ralf Corsepius 2016-03-22 06:30:18 EDT
IMO, this patch should fix this FTBFS:

# diff -Naur hydrogen- hydrogen-

        std::string playlistInfoFile = patternname;

                return NULL;

And I can confirm it does.
Comment 7 Adam Stylinski 2017-07-26 16:57:09 UTC
The suggested patch should also be backward compatible with older GCCs using older STL implementations.  Can someone either make this ebuild allow for user patches or add this patch to the upstream ebuild?
